X-ray vs. MRI: When Do You Need Each Imaging Test?

When it comes to diagnosing orthopedic conditions, imaging tests are a vital piece of the puzzle. But with different options available, many patients wonder: when do you need an X-ray, and when is an MRI the better choice? At Vail-Summit Orthopaedics & Neurosurgery (VSON), advanced imaging services help ensure patients receive the right test at the right time for the most accurate diagnosis and treatment plan.

The Role of X-rays

X-rays are often the first step when evaluating an injury or source of pain. They use low levels of radiation to create quick, clear images of bones and joint alignment.

X-rays are best for:

• Identifying fractures and broken bones

• Detecting arthritis and joint degeneration

• Evaluating bone alignment or dislocation

Because X-rays are fast and widely available, they’re usually the go-to choice when a bone injury is suspected. However, they don’t capture soft tissues like muscles, tendons, or ligaments in detail.

When an MRI Is Needed

Magnetic Resonance Imaging (MRI) provides a much more detailed look inside the body using powerful magnets and radio waves. Unlike X-rays, MRIs don’t use radiation, making them safe for repeated imaging when necessary.

MRIs are best for:

• Detecting soft tissue injuries (ligaments, tendons, cartilage, muscles)

• Identifying meniscus tears or labral tears

• Spotting stress fractures that may not show up on X-rays

• Evaluating complex joint injuries or unexplained pain

MRI scans take longer than X-rays and require patients to remain still during the procedure, but the detailed images often give doctors critical insight into injuries that aren’t visible on X-rays.

How Your Doctor Decides

Choosing between an X-ray and MRI depends on your symptoms, the type of injury, and what your care team needs to see. For example, a suspected wrist fracture may start with an X-ray, but if pain persists and no fracture is visible, an MRI could be the next step to look for soft tissue damage.

Advanced Imaging at VSON

This allows your care team to quickly determine the source of pain and create a treatment plan tailored to your needs. Contact our team today to learn more.

The Bottom Line

X-rays and MRIs are both valuable diagnostic tools, but they serve different purposes. X-rays are ideal for evaluating bones, while MRIs excel at capturing soft tissue details. With access to advanced imaging at VSON, you can feel confident knowing you’ll receive the right test, and the right treatment to get you back to the activities you love.
